DRINKING-CUP.

Application filed November 15, 1909. Serial No. 528.007.

To all whom tt may concern:

Be it known that I, ALFRED R. HUssEY, of Harvard, Worcester county,State 'of lowing is a specitication.` This inventlon relates to drinkingcups,

and then thrown away, being thereby especially well adapted for use inpublic places where sanitary drinking cups are required.

Prior to this invention drinking cups have been made of paper, but insome instances the cost of vmanufacture has been too great tg permitofthe cups being used once and then thrown'away'; vin other instancesthe construction has been such that the parts composing it becameseparated either before or while in use.'

A drinking cup, even of the cheap form herein referred to, mustbeself-supporting when in upright position, 4so that when, placed on ashelf beneath a faucet, fit is not necessary to hold it, hencea cup musthave a substantially rigid bottom even though its, upright walll isflexible.

The object of this invention is to improve of. the cup, whereby the cupwill be selfsupporting when in upright position, and the parts composingit will not separate, as,v for instance, the bottom will notl fall out,either before or while in use, yet it may be made cheap enough to beused once and then thrown away, thereby adapting it for use as asanitary drinking cup well suited for public places.

Figure l is a side elevation of a drinking cup embodying this invention,Figs. 2 and 3 are enlarged vertical sections of the bottom portion ofthe cup, Fig. 4 is a plan view of a blank composing the bottom-piece,Fig. 5 is an enlarged side view of a portion of the shape to be used inthe manufacture of the dotted line 6, Fig. 2, Fig. 7 is a plan View ofthe blank compo-sing a modified forin of bottom-piece, and'Fig. 8 4is anedge-view of the bottom-piece composed of the blank shown in Fig. 7.

a. represents a tubular conical, or it may be cylindrical, body, whichis composed of a sheet of paper bent into tubular form and its edgesoverlapped and glued or otherwise secured together, as at a.

,"lhe bottom piece which I employ consists of a circular flat disk Z)having its margin cut or formed with inter-dental spaces b', arranged atregular distances apart, thereby forming teeth b2. As shown in Figs. 4,and 5 said spaces may be formed with substantially parallel sides, or,as shown in Figs. 7 and 8, may be 'V made V-shaped. When formed withparallel sides the teeth b2 are dovetailed in shape, and when made V-shaped the teeth b2 have parallel sides. Said teeth b2 are then turneddown to form a broken or toothed flange extending entirely l around thebottom-piece, care being taken to preserve the interdental spaces. Theteeth are bent downward at their junctions with the central part of thedisk, so thatv the material at the edge of the central part of the diskbetween the `teeth extends across the tops'of the interdental spaces.The bottompiece thus constructed, andwith its teeth arranged on itsunder side, is then forced into the tubular body from the top toward thebottom until the ends ,of the teeth occupy positions flush .with thelower edge of the tubularbody or thereabouts, and when so disposed thetubular body will be pressed outward' slightly to form in it a groovewhich receives the edge of the bottom-piece, at the junction' of thecentral portion thereof and toothed tiange, said groove beingrepresented at c and also when so disposed its interdental spaces b arestill preserved. The bottom-piece is made of quite sti paper orcardboard and hence is springy, so that its marginal teeth have aninherent tendency to spring outward and thereby closely engage the lowerend of the tubular body. The bottom-piece is thus Very securely heldinposition byjfriction, yet additional means are provided for securingthe bottom-piece in position as well as for sealing the joint betweenthe bottom-piece and the tubular body. The additional means consists ofa coating of paraffin-wax or equivalent material applied to the entireexternal surface of the cup. The paraffin-wax may be melted and appliedin the form of spray, after which it congeals and forms a very solid loscoating on the cup. It fills, or at least partially 1ls. all theinterdental spaces between the marginal teeth on the bottompiece, asshown at d, and `thereby assists in securing the bottom-piece to thebody, and particularly serves to resist downward move ment of thebottom-piece by` forming abutments beneath it. so that they are embeddedinit and are therebysecurely held', and, furthermore, the portions ofthe central part of the disk which extend across the tops of theinterdental spaces are supported by the waX beneath them. v

The completed cup is waterproof; is sufficiently cheap to manufacture topermit of its being used once and then thrown away; it has a flange atthe bottom which is very stiff; it has a rigid bottom-piece whereby ityis self-supporting in upright position; and its parts will not becomeseparated before or while being used. u

Obviously the cup may be employed for other than drinking purposes.

I claim:

A drinking-cup consisting of a tubular It also covers the teeth body anda circular disk having a downwardly-extending toothed iange withinterdental spaces between the teeth thereof, said disk being arrangedat the lower end of said body with the ends of the teeth of the flangethereof flush with said lower end of the body and a coating lofparalin-wax entirely covering the external surfaces of said body andbottoni-piece, which fills the interdental spaces and embeds the teeth,thereby waterprooing and stifening the cup and sealing the joint atthebottom, and providing abutments in the interdental spaces, beneath tlieedge of the bottom-piece, which assist in securely holding saidbottom-piece in posi tion, substantially as described.

In testimony whereof, l have signed my name to this specification, inthe presence of twor subscribing witnesses.
